F to Ab is a minor third (3 semitones), Ab to C is a major third (4 semitones), C to E is a major third (4 semitones). A minor triad with a major seventh, E, a half step below the root. The minor third Ab and the major seventh make an augmented triad (Ab C E) inside the chord, which gives it its tense, suspenseful sound.

The E-shape and A-shape grips are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play minor-major seventh chords on other roots.

Where Fm(maj7) fits

Fm(maj7) is i(maj7) in F minor. Most often it is a passing chord in the descending line Fm → Fm(maj7) → Fm7 → Fm6, where one voice falls a half step at a time from F. The first four bars of the jazz standard "My Funny Valentine" (Cm, Cm(maj7), Cm7, Cm6 in C minor) are exactly that line.
